Tomb is a lightweight encryption tool for managing encrypted containers. It’s ideal for backing up password files somewhere on the Internet since you keep the keyfile separate, like on your USB memory drive. With the release of Google Drive, Google has provided an excellent service for your Tomb files (in tandem with Google Authenticator, a free multi-factor authentication service, you can better secure your Google-managed data). Ubuntu One is another cloud-based service which is also free.
